The board draws power from a combination of 2pin ATX and 8-pin EPS power connectors and offers 6-phase VRM for the CPU. You get four DDR4 memory slots, one PCIe 3.0 x16 slot (electrical gen 3.0 x4), three PCIe 3.0 x1 slots and two legacy PCI slots.
Storage connectivity includes an M.2 32 Gb/s slot, a SATA-Express 16 Gb/s connector, and six SATA 6 Gb/s ports. Display outputs include one each of DVI, D-Sub, and HDMI 2.0 connectors. USB connectivity includes two USB 3.1 ports (both type-A and on the rear panel), and six USB 3.0 (four on the rear panel, two by header), and four USB 2.0/1.1 ports by header. 6-channel HD audio with ground-layer isolation, and Realtek gigabit Ethernet make for the rest of it.
